Exporting from EndNote to NVivo assigning the property abstract a style

Dear,
I own Endnote X7.7.
I will simulate the process and present what I need.

Step 1
I selected the first two papers to export to NVIVO.
So far no problem. Step1.jpg attached.

Step 2
After importing into NVIVO the result is the one according to Step2.jpg in the attachment.

Step 3: The problem
I would like the Qd I export from Endnote to assign a Title style style, as word does, to {abstract} property. This would allow me to make better use of the functions that NIVV allows me to do. Step3.jpg attached.

Question: How do I apply a title type style to the {abstract} property in endnote before exporting to xml?

Grateful,
